Digimaster feedback

FYI for persons that are thinking of buying. I brought my Digimaster 3 from Obd2tool.com and also the following is my expertise with it so far:

1.The shipping is extremely fast. I paid via Paypal, and received the unit inside four days. I live in US-CA
2. It arrived with adequate packaging.
3. Initially, the Digimaster 3 unit will boot up in locked state asking for registration. You have to make contact with seller (paypal address) to acquire an account and password ahead of you are able to use it.
4. Immediately after you’ve the account data, it requires about 3+ hours for the method to execute on the internet update, depending your online speed plus the Digimaster remote server situation. I had to monitor my unit and repeat the update couple of occasions to finish the process. I have a 12mbps Down/1.5mbps Up link net. During update download, system would cease at some measures and timeout. Once restart it’ll resume and continue download the remaining measures. If onscreen keyboard doesn’t show, there is a hardware button to bring it up.
5. As soon as update is completed, I checked my system’s value list choice to determine what possibilities are unlocked for me: all most all selections are UNLOCKED. My account starts with 200 tokens. Following speak to seller, he confirms that all possibilities will be unlocked as soon as they fully release it. The tokens are for testing and trail goal.
6. Right after I started to test it on cars, I’ve encountered problems. I am at the moment operating with seller to resolve them. Crossing my fingers that this technique will provide what it promised.

2017 Original Digimaster 3 Odometer Correction Review

Recently, I purchased a 2017 Original Yanhua Digimaster 3 odometer correction master, which gave me great help.

This is my story. In fact, several days ago, I have been in the trouble that I don’t know how to change the mileage for my lover,Fiat Punto 2003. What even worse is that I’m a quite lazy person and have little knowledge of programming. Therefore, I asked for help in the forum and hoped that someone can give me suggestions.

What a lucky man I was! A guy who was enthusiastic and patient recommended a odometer correction tool named Digimaster III. Followed his advice, I purchased the master on cardiagtool.co.uk with €1,200 and 4 days free delivery. It’s a package weighed 6.5kg including Digimaster 3 host, 12V switch power supply and varieties of adapters and cables,etc. You know what! This tool doesn’t need activate and the installation has been completed by the nice customer service.The after-sales service also provided all life long Free update every 2 month and solutions for any problem during the usage.


The using process is not going quite well.I entered with digiprog 189.000 as new mileage. but car shown only 18.900km.It was very strange. I opened my mileage calculator and I saw that there were 2 kinds of dashboards for this car. I tried both eeprom-codes to write manually. The first one calculated 189.000km, but still the car said 18.900 Then I tried the second one calculated 189.000km, and the car also said 189.000.

Luckily, all the problems are solved. My experience with Digimaster 3 on OBD2TOOL is totally satisfied. I become more confident with my learning ability. I was told that D3 also have the function of audio decoding, immo test, ECU program, etc. I think I will try in the future.
